In the framework of the European Alien Species Information Network (EASIN; http://easin.jrc.ec.europa.eu/), an inventory of marine alien species in Europe was created by critically reviewing existing information in 34 global, European, regional and national databases. In total, 1369 marine alien species have been reported in the European seas (including 110 cryptogenic and 139 questionable spec...

Gasotransmitters are biologically produced gaseous signalling molecules. As gases with potent biological activities, they are toxic as air pollutants, and the sulfurous compounds are used as fumigants. Most investigations focus on medical aspects of gasotransmitter biology rather than toxicity toward invertebrate pests of agriculture. In fact, the pathways for the metabolism of sulfur containin...

This dataset provides information on specimens of harvestmen (Arthropoda, Arachnida, Opiliones) collected in French Guiana. Field collections have been initiated in 2012 within the framework of the CEnter for the Study of Biodiversity in Amazonia (CEBA: www.labex-ceba.fr/en/). This dataset is a work in progress.  Occurrences are recorded in an online database stored at the EDB laboratory after ...

Pentastomids are a small group of vermiform animals with unique morphology and parasitic lifestyle. They are generally recognized as being related to the Arthropoda; however, the nature of this relationship is controversial. We have determined the complete sequence of the mitochondrial DNA (mtDNA) of the pentastomid Armillifer armillatus and complete or nearly complete mtDNA sequences from repr...

Evolution of segmented limbs is one of the key innovations of Arthropoda, allowing development of functionally specific specialized head and trunk appendages, a major factor behind their unmatched evolutionary success. Proximodistal limb patterning is controlled by two regulatory networks in the vinegar fly Drosophila melanogaster, and other insects. The first is represented by the function of ...

Recent advances in molecular phylogenetics and morphological cladistics have considerably changed the picture we had on the tree of life (e.g. see Refs [1–16]). In particular, the alteration of the evolutionary relationships between eukaryotic organisms have split some traditional clades (e.g. Protozoa, Protophyta, Acoelomata, Aschelmintha) into highly divergent new branches, and have gathered ...

A database providing information on mosquito specimens (Arthropoda: Diptera: Culicidae) collected in French Guiana is presented. Field collections were initiated in 2013 under the auspices of the CEnter for the study of Biodiversity in Amazonia (CEBA: http://www.labexceba.fr/en/). This study is part of an ongoing process aiming to understand the distribution of mosquitoes, including vector spec...

Collembola merupakan kelompok Arthropoda yang sangat beragam dan memiliki fungsi penting di dalam ekosistem tanah. Namun, kelimpahan keanekaragaman Kalimantan Barat masih sedikit dipelajari. Tujuan penelitian ini adalah untuk mendapatkan informasi Collembola, serta hubungannya dengan faktor lingkungan. Sampel dikumpulkan pada Desember 2016 Februari 2017. dari hutan alami, karet, kebun kelapa sa...

Knowledge of food resource of the houbara which an endangered species would be a important step toward the preservation of this bird. Adequate study has not been done in this field and therefore the food sources of the houbara during the brooding season was studied in the central steppe of Iran. In order to determine the density of insect in plant communities the pitfall trap was used , positio...
